Well…
A benefit of the budget cuts and reduced cast is that the narrative seemed more focused.

Had this been a “typical” season, I speculate there’d be side plots and melodrama involving Kyle, John Henry, Natalie, et. al. But the downside of budget constraints is that Smallville comes across as insulated and isolated —too small a stage for the action. I.e., it might be imagined that the Death of Superman would be/should be worldwide news. Though, to be fair, maybe that’s coming.
And the “
missing heart” business initially struck me as an odd plot conceit. After the first shock of Supes’ death, Lois and the boys seemed to pretty quickly understand that resurrection was feasible by restoring the heart. But while this may have been common knowledge to the
characters, I (as audience) felt some vital info/exposition had been skipped over. Admittedly, the search for the missing heart is now a plot MacGuffin. So I guess it works at that level. (I presume that the one destroyed was a fake.) Also: at first, it wasn’t clear to me that Supes was
sans heart. (Perhaps the CW decided that a gaping chest wound was too graphic for the network?) And later, when Doomsday delivers the organ to Luthor, I still wasn’t sure what it was supposed to be. It did look vaguely fleshy and gruesome. But not particularly heart-like.
